Struct Counter

source
pub struct Counter<T> {
    pub removals: u32,
    pub insertions: u32,
    pub wrapped: T,
}
Available on crate feature blob only.
Expand description

A Sink which wraps a different sink and counts the number of removed and inserted tokens.

Fields§

§removals: u32

Total number of recorded inserted tokens. Computed by summing the lengths of the after subsequences pass to process_change.

§insertions: u32

Total number of recorded inserted tokens. Computed by summing the lengths of the after subsequences pass to process_change.

§wrapped: T

The Sink for which the counter records tokens. All calls to process_change are forwarded to the sink by the counter. After finish is called, this field contains the output returned by the finish method of the wrapped Sink.

Implementations§

Trait Implementations§

source§

impl Default for Counter<()>

source§

fn default() -> Counter<()>

Returns the “default value” for a type. Read more
source§

impl<S> Sink for Counter<S>
where S: Sink,

source§

type Out = Counter<<S as Sink>::Out>

source§

fn process_change(&mut self, before: Range<u32>, after: Range<u32>)

This method is called whenever a diff algorithm finds a change between the two processed input file. A change is a continous subsequence of tokens before that needs to be replaced by a different contious subsequence of tokens after to construct the seconds file from the first. Read more
source§

fn finish(self) -> <Counter<S> as Sink>::Out

This function is called after all calls to process_change are complete to obtain the final diff result
source§

fn with_counter(self) -> Counter<Self>

Utility method that constructs a Counter that tracks the total number of inserted and removed tokens in the changes passed to process_change.
